To allwhomt concern.' y

Be it known that I, EDWARD C. GLEDHILL,

i a citizen of the United States, residing at diatel Galion, in the county of Crawford and State of Ohio, have invented certain new anfl use' ful 'Improvements in Unloading Apparatus, of which lthe following is a specification.

This .invention relates to apparatus for unloading freight cars containing stone, coal, sand, or similar material and transfei'lng the load to a bin from which it may be discharged into wagonsor other conveyances to be tra orted to the place of use. One object of e invention 1s to provide an apparatus which may be easily lnstalled and anotherfobjectl` of the invention is to provlde means whereby` the bin and the parts immecoacting therewith may be easily trans, erred from one point to another so as to permit the mloading of a number of cars successively. `-A particular object of the 1nvention is to provide meansfor posltively delivering the stone-or other material from a Vpoint beneath the carto an elevator by which it is transferred to the bin, and another objet of the 'invention is to provide .a novel construction whereby the elevator may be brought into a reduced compass to permit the travel of the bin.

All these stated obects. and other oblects which will incidenta y'appear are attained in the ap aratus. illustrated inthe accoman in .cgrlizlagln novel ticularly pointed out in the claim following they detailed description. 4

In the drawings: y F' re 1 is a view artly in elevation and partlfyu in section of t le complete'apparatus; Fig. 2 is an end view of l.the elevator; Fig. 3 is a pe ectiveview off the hopper rom l or receptacle` which receives the load the car; ,y Fig. 4 is a detail view of. a portion of the drag chain or feeder;

Fig. 5 is a detail view of aclosure for the receptacle or hopper.; l n

Fig. 6 is a detail perspective viewof the feeder whichA operates in the bottom of the umliimlrrymge" c t' i 'd ca ou m mven ion rovi e 1 and between the 1iziesby below the track rawings and the invention resides' features which will be par which said track is supported, a hopper or receptacle 2 which is of such dimensions as to extend entirely across the bed of the track and is adapted to receive the stone or other material from the car. This hop err or receptacle may be of any preferre material and will generally be constructed of metal inorder to attain durability. In the to of the rece tacle, adjacent andparallel wit one side o the same, are a series of o enings 3 which are adapted to be close by doors 4, said doors being hinged at the far sides of the openings an supported by bolts or similar ctches. 5 ag theneardsilefs of thlel openlngs. spring` 1s rovi or eac door and bears against thep under side of the same so as to normally hold the door in its raised closed position. The bolt` or catch 5 is preferably a sliding bolt connected by a link 7 with a lever 8 ivoted upon the hopper or receptacle an having an operating cable or other medium `9 attached to its free end. The said cable 9 extends to the end of the receptaclewhere it may be easily grasped by the o erator and the several doors are provide with Similar levers and operating means so that each door may be o ened independently of all the other doors.

he` bolt may be mounted on the under surface of the top of the receptacle and the pin connecting the link 7 with the lever 8 may extend through a slot in the said other convenient arrangement may adopted so as to accommodate the parts and permit them to be operatively connected. The lever 8 may beconnected ,with a:j spring 10 so that, when the cable 9 is released, the lever will at once return to its normal osition and the'bolt be carried under the ree edge of the door. The spring 6 should be strong enou h to support the door in its raised or close osition under normal conditions so that, wl en the stone or other material ceases top or any to owfthe door will at once return to its closed position so thatthe door opening will not remain uncovered and persons walking along the track or near the hopper will not be liable to be injured by fallin or tripping u on the openin When the oor-is in its v c osed position, t e bolt 5 willproject under the free end of the door so as to support it a pull is exerted upon the cable 9 to retract the bolt. It will thus be seen that the operator may open one or more of the inlets to the hopper or receptacle, according Ato the direction in which tie load is discharging from the car, so that the material will not pass into the hopper too rapidly and exert a strain upon the ceder beyond the capacity of the saine.

The near end of the receptacle is open, as shown in Fig. 3, and from the bottom of the said receptacle projects a' hopper or trough 11 in which the lower bight of the elevator is disposed. In the lower end of the elevator frame is journaled a `transverse shaft 13 equipped with a sprocketwheel 14 at one end. A chain 15 is trained around said sprocket and a sprocket 16 on the end of a shaft 17 which is journaled in'one side of the receptacle :2 and in a partition 18 within said receptacle, the inner end of said shaft 16 being equipped with a beveled pinion 19, vas shown clearly in Fig. 3. This beveled pinion 19 meshes w'ith a beveled gear 20 on a "ertical shaft 2l which is journaled in the top and bottom of the receptacle 2. Adjacent. the lower end of the said shaft 21 is a sprocket wheel 22 around which is trained a drag chain 23. This drag chain passes also around a sprocket wheel 24 at the lower end of a shaftI 25 journaled in the top and bottom of the receptacle and the altern-ate links of the chain carry outstandin arms 26 which arem'so disposed as to ri e over the bottom of the receptacle and thereby push the stone or other material through the open end of the receptaclel into the trough 11. These arms 26 may be of any convenient construction and ai'c illustratedas constructed of stout rods bent substantially into V- form having one ,side radial to the chain and the other side acting as a brace for the said radial side. The radial side will strike squarely against the material and push the same from the receptacle while the inclinedY on brace side will aid the said material'- lengaging side in resisting the bending strain.

The construction moreover will'per'mit the arms to spread slightly or yield to the bending or change of position of the chain as it passes around the sprocketwhe'el's. A partition 27 extends longitudinally ofV the receptacle between the plane of the door openings and the plane-of the drag chain so that the material will be prevented from falling over onto and between the runlsof the drag chain and thereby clogging the operation o f the a p paratus.

The elevator is supported from the bin 28' bv links or arms 2th 30. 31 which are vpivotallv attached to the bin andto vthe. elevator frziine. as `wilLbe readily understood. The elevator frame is constructed in two m11111- bei's or .sections connected by a binge. as iiithe upper end of the elevator and vis suprted from the elevator frame by a link or race 34, as will be readily understood The elevator is driven by a shaft. which is journaled in the sides of the elevator frame and extends across the same between the runs of the apron 36 carrying pockets 37 which constitute the carrying member of the elevator. The said shaft 35y is equipped with a pulley 38 at one end around which is trained a belt l39 which also passes around a pulley 40V onthe driving shaft of; a motor M mounted upon the lower portion of the bin. The shaft 35 carries a pulley or sprocket wheel 41 at the end opposite the pulley 38 and a chain or cable 43 is trained around the said member 41 and a similar member 43 at the upper end of the elevator. Motion is imparted to the apron from the shaft 44 carrying the pulley or sprocket Wheel 43 and the consequent travel of the apron imparts rotation to the shaft 13 which carries the roller 45 around which the lower part ofthe apron passes. A drum or windlass 46 is mounted upon the bin and equipped with a crank or other handle 47, a cable 48 being Wound upon and secured to the said drum and 'passing therefrom to the elevator to which it is secured near the lower end thereof, as indicated at 49. It will now be readily understood that the elevator is driven from the motor M which may be a gasolene engine or of any other preferred type. If the chain 15 be disconnected and the ink 31 released at one end, the cable 48 maybe wound upon .the'windlass 46 and the lower end of the elevator thereby drawn upwardly and in- Wardly toward the bin, the links 29 and 30 swinging up and over so that the elevator .frame may fold upon the hinge 32 and lie close to and uponthe bin, as shown-by dotted lines in Fi 1. It is also to be noted that the bin wi l preferably have Vits sides constructed in two sections connected by hinges 50 so ,that` the 'said sides may be folded tov iio to place and vthe usual discharge spout 52 is provided whereby the contents of the bin may be discharged-into wagons or other conve ances.

y `he operation and many advantages of my improved apparatus are thought to be apparent from the foregoing description, taken in'connet'tion with the accompanying drawings. 'and further detailed reference thereto 'is de'enu-rd unnecessary.

. Having thus described the invention, what is claimed as new is:

In an apparatus for the purpose set forth,

the combination of a portable bin having 5 foldable sides, an elevator swingingly sup-` ported from said bin and consisting of sections hinged together at their meeting ends whereby it may be swunl close t0 and fold over the bin, a drum on t e bin, and a cable wound upon the drum and secured to the 10 elevator nearthe lower end thereof.

In testimony whereof I aiiix my signature.
